Abstract: In wireless communication, channel equalization is one of the most challenging tasks because the broadcast channels are often subjected to multipath fading and several bandwidth limitations. Our project is mainly concerned with the Single Carrier Long Term Evolution (SC-LTE) uplink system model and its performance analysis when Fractionally Spaced Constant Modulus Algorithm (FS-CMA) and Recursive Least Squares Algorithm (RLS) are implemented. FS-CMA (CMA (1, 2) and CMA (2, 2)) and RLS algorithms are used individually to eliminate noise caused by multipath fading and Additive White Gaussian Noise (AWGN) in the stationary channel. The performance of conventional FS-CMA and RLS algorithm are compared using Bit Error Rate (BER) vs. Signal to Noise Ratio (SNR), Convergence, Equalizer output, Peak to Average Power Ratio (PAPR) vs. SNR
